Basically the total of the line or any line is 180°

which means x = 51°
(0.0974, 0.1226)
Step-by-step explanation:
We first find the sample proportion;
255/ 2373
0.11
The Z value for a 95% confidence interval is 1.960
Therefore;
0.11 +- 1.96 * √ (0.11(1 – 0.11))/2373
0.11 +- 1.96 * 0.00642
0.11 +- 0.0126
= 0.1226
= 0.0974
(0.0974, 0.1226)
